laply is part of what package in R?

Question

laply for R is part of what package?

I get:

 \"Error: could not find function \"laply\"\".

Thanks.

Answer 1

A useful way to find functions that are somewhere in some contributed package on CRAN is

install.packages("sos")
library("sos")
findFn("laply")

(of course, the first command is only necessary once per R installation ...)

In this case, you get

> findFn("laply")
found 5 matches

and a web page opens in your web browser that shows you (as stated above) that there is an laply function in the plyr package.

Of course, findFn() is much more broadly useful -- for example, you could try findFn("compositional data analysis") (if that was what you were interested in).
